GAS-METER CASING.

SPECIFICATION forming part of Letters Patent No. 505,715, datedSeptember 26, 1893.

Application filed September 14, 1892- Serial No. 445,890. (No model.)

To all whom it may concern.-

Be it known that I, WILLIAM N. MILSTED, a citizen of the United States,and a resident of New York, State of New York, have invented certainImprovements in Gas-Meters, of which the following is a specification.

The object of my invention is to improve the construction of gas meters,my invention relating especially to the construction'of the casing andthe permanent parts of the meter to which the working parts areattached.

In the accompanying drawings:Figure 1, is a perspective view of a meterillustrating my invention, with a box attached containing the ordinaryregistering mechanism. Fig. 2, is a detached perspective view of thecasing without the heads or internal partitions. Fig. 3, is a detachedperspective view of one of the heads, the transverse partition, and thetable, with some of the working parts carried thereby. Fig. 4, is asectional plan view on the line 1-2, Fig. 1, all working parts beingomitted; and Figs. 5 to 12, are views illustrating modifications of myinvention.

The main object of the present invention is to dispense with packing andto permit the main joints to be soldered from the outside of the casing.

Referring to Figs. 1 to t of the drawings, A is the casing which may bequadrangular or cylindrical as desired and in the sides of said casingare two vertical slots a, for the reception of the vertical partitionplate B, the ends 5 b of which extend through the slots. The partitionplate B, as shown in Fig. 3, is preferably secured to the bottom head Gand to the table D upon which are mounted the valves of the meter.

As shown in Figs. 1 and 3, the bottom plate 0 has a flange c whichoverlaps the bottom of the casing A and the ends I) b of the partition Bare bent over as shown in Fig. 4 to form T- flanges b.

When the casing is slipped over the table D and the partition B and intothe flanged bottom head 0 it is ready for soldering, the solder beingfirst applied around the bottom and then up each side where thepartition projects through the casing, as clearly shown in Fig. 4:, sothat the important solder joints are made on the exterior of the casingafter the bellows and valves are in position upon the partition andtable. The table is soldered in position before the cap or cover plate Eis secured. I-Ience all the solder joints necessary in a gas proof meterare made after the parts are in their relative positions.

Heretofore it has been a difficult task to stop a leak from one chamberto the other between the edge of the vertical partition plate and thecasing after the meter was put together, but by the constructiondescribed such leaks may be stopped both cheaply and expeditiouslywithout taking the meter apart.

The partition in someinstances may simply extend through the slottedcasing, as shown in Fig. 5, projecting enough to provide for a solderjoint on each side of the casing.

In Fig. 6 I have shown the partition plate provided with a simpleL-flange instead of the T-flange shown in Fig. 4., and in Fig. 10 I haveshown such partition combined with a casing recessed at the oppositesides for the reception of the flanges so that the solder joints do notform projections on the sides of the casing, while in Fig. 7 I haveshown a meter divided so as to use three diaphragms, it being understoodthat the meter may have as many divisions as desired, without departingfrom my invention.

In Fig. 8 I have shown my invention as applied to a quadrangular meter,and in Fig. 9 I have shown a vertical sectional view of a meter in whichthe bottom head is inserted within the casing with the flange turneddownward to facilitate riveting the two together or the flange may beturned upward if desired.

In that class of meters where the gas conveying pipes are at the sidesof the meter casing instead of passing through the top, as shown in Fig.1, said pipes may incase and protect the joints between the partitionplate and casing, as shown in Fig. 8, so that any gas which escapesthrough the slots owing to defective soldering will simply pass into thetubes.

It is not necessary that the ends of the partition should in all casesproject through the slots in the casing, or even that the casing shouldbe slotted throughout the length of the partition, as said partition mayhave at the ends a flange such as shown for instance at b in Fig. 11,such flange closing either a slot, or a row of perforations a as in Fig.11,

- or a row of elongated openings a as in Fig.

12, the soldering of the partition to the easing being effected bysolder introduced from the outside through such slots, perforations, oropenings.

Having thus described my invention, I claim and desire to secure byLetters Patent 1. The combination of a meter casing having openings inits sides with an internal partition plate, having its side edgesexposed through said openings, and secured to the easing by solder,externally applied, substantially as specified.

2. The combination of the meter casing havin g slots in its sides, witha partition plate separating the easing into two or more compartmentsand projecting through the slots, said projecting portions being securedto the casing by external solder joints, substantially as described.

4. The combination of a casing having openin gs in its opposite sideswith a partition plate or plates, the side edges of which are exposedthrough the openings, said partition plate or plates dividing the casinginto two or more compartments, a table mounted on said partition plateand a bottom-head secured to the lower edge of the partition, the latterwith its table and bottom edge, being attached to the casing by solder,substantially as described.

5. The combination of the casing having openings in its sides, and thepartition plate dividing the casing into two or more compartments andsecured to said casing by externally applied solder, with strips ofmetal soldered at their edges to the outside of the casing on each sideof the partition joints, so as to form channels or pipes for conveyinggas to or from the meter and concealing and protecting the partitionjoints, substantially as specified.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

WILLIAM N. MILSTED.
